Book Description
Our modern idea of what a healthy landscape looks like and how it functions is distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. Goldfarb shares the powerful story about one of the world's most influential species. He explains how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. -- adapted from jacket

Book Description
By the end of the 19th century both beaver species had been extirpated from large portions of their native ranges. The global decline in beaver populations was the direct re sult of exploitation by humans. Now, at the end of the 20th century, protection, manage ment, and reintroduction programs, coupled with a decline in the demand for beaver fur and other products, have allowed beaver populations to increase dramatically. Since bea vers actively modify their local environment their activities can conflict with human land use. Because of this, the beaver, once considered a unique and exotic component of wet lands, is now often considered a nuisance species. The history, as well as the current status, of beaver populations in Europe and North America provide insight into how con servation programs work, and into how humans and wildlife interact. The initial plenary lecture of the Euro-American Mammal Congress (July, 1998) was presented by Dr. Michael L. Rosenzweig, a professor at the University of Arizona. Dr. Rosenzweig discussed how humans have used and continue to use natural resources, in cluding wildlife and wildland. He provided evidence indicating that the current model of reservation conservation could not provide a long-term solution to the human-wild life/wildland conflict. Dr. Rosenzweig emphasized that what is required is a move away from purely exploitive activities (I would call this exploitive ecology) and the develop ment of a reconciliation ecology with wildlife.

Book Description
“Unexpectedly delightful reading—there is much to learn from the buck-toothed rodents of yore” (National Post). Beavers, those icons of industriousness, have been gnawing down trees, building dams, shaping the land, and creating critical habitat in North America for at least a million years. Once one of the continent’s most ubiquitous mammals, they ranged from the Atlantic to the Pacific, and from the Rio Grande to the edge of the northern tundra. Wherever there was wood and water, there were beavers—sixty million, or more—and wherever there were beavers, there were intricate natural communities that depended on their activities. Then the European fur traders arrived. Once They Were Hats examines humanity’s fifteen-thousand–year relationship with Castor canadensis, and the beaver’s even older relationship with North American landscapes and ecosystems. From the waterlogged environs of the Beaver Capital of Canada to the wilderness cabin that controversial conservationist Grey Owl shared with pet beavers; from a bustling workshop where craftsmen make beaver-felt cowboy hats using century-old tools to a tidal marsh where an almost-lost link between beavers and salmon was recently found, it’s a journey of discovery to find out what happened after we nearly wiped this essential animal off the map, and how we can learn to live with beavers now that they’re returning. “Fascinating and smartly written.” —The Globe and Mail (Toronto)
